Are you doing a double-take?

Lindsey Gort, who’ll play young Samantha Jones on the second season of “The Carrie Diaries,” is a dead-ringer for Kim Cattrall (inset) — who originated the role of Samantha on HBO’s long-running series, “Sex and the City.”

In the upcoming season of “Diaries,” premiering Oct. 25, Carrie Bradshaw (AnnaSophia Robb) will encounter Samantha, who ends up being one of the most important people in Carrie’s life.

Young Sam, who’s described as a “beautiful and sexy young woman,” hails from the Florida panhandle — and has already made a name for herself in wild and woolly ’80s-era New York City.
